MIKE GRAVEL, Vietnam War Era senator from Alaska (who knew he was running for president?), used the Democrat debate last night very constructively. He showed the illuminating power of politics. “We spend more on defense than the rest of the world put together. Who are we afraid of? . . . Iraq has never been a threat to us. We invaded them. . . . The Military Industrial Complex not only controls our government lock, stock and barrel, but they control our culture.”
